Can someone please explain "Send MIDI Controllers" on page 121

[mudpuppy]

Here's what im trying to do:

• Press play on an Ableton sequence

• Turn some knobs on my Nord

• Sequence is now finished - go back to the beginning of the sequence and press play to listen to the CC values I've recorded

• I want it to sound exactly like what happened when I recorded...but the CC values are all still at the places that I left them when I finished the first sequence

I'm sending MIDI Controllers in the menu dive...but I don't understand where this information is going. How does Ableton read this information?

The knobs on synths generally don’t send controller data, which is standardised functionality adopted by all manufacturers.

Front panel controls tend to be unique to every machine, which is why they’re sent via machine-specific protocols called “SysEx” (system exclusive). You need to make sure that your keyboard is sending SysEx data (use a MIDI monitoring application on your computer to check), and that Ableton Live is set up to record and play back SysEx.
